Parkinson's disease decisions — 2026

The Board has granted service connection for Parkinson's disease and determined that the Veteran's cause of death was due to his service-connected Parkinson's disease. The decision is based on evidence showing exposure to hazardous materials during active duty, which is considered direct service connection.

The Board has granted service connection for PTSD, finding that the Veteran's diagnosed PTSD is related to his in-service stressor. The rating of 100% (total disability) was assigned due to the severity of his symptoms and conditions.

The Board has remanded the case due to an inadequate VA examination and opinion regarding the etiology of the Veteran's Parkinson's disease. A new VA examination by a qualified clinician, preferably a neurologist, is required.

The Veteran's service connection claim for myoclonus, Parkinson's-like condition, and essential tremors is denied as his symptoms are encompassed by his existing service-connected abnormal brain MRI (bilateral basal ganglia lesions, ventriculomegaly, and moderate atrophy) with REM behavior sleep disorder and periodic limb disorder.
